    A pentane gas catalytic bead sensor is a type of gas sensor that is commonly used to detect the presence of pentane gas in the environment. The sensor works by using a small bead made of a catalytic material, such as platinum, that is coated with a special catalyst that reacts with pentane gas. When pentane gas comes into contact with the catalytic bead, it causes a chemical reaction that generates heat, which is then detected by the sensor. The amount of heat generated is proportional to the concentration of pentane gas in the environment, allowing the sensor to provide a quantitative measurement of pentane gas levels.
